Evaluation of Ozone Formation Potential of Formaldehyde Using Smog Chamber Data
Aerosol and Air Quality Research, 2023 Formaldehyde (HCHO) is one of the important O3 precursors in the atmospheric environment, but the mechanism for HCHO photochemical reactions is not very clear now. In the present study, the effects of relative humidity (RH) and initial VOC/NOx ratio (RCN)

A ‘receptive’ boundary layer [PDF]
Journal of Fluid Mechanics, 2010 Receptivity is the process which describes how environmental disturbances (such as gusts, acoustic waves or wall roughness) are filtered by a boundary layer and turned into downstream-growing waves. It is closely related to the identification of initial conditions for the disturbances and requires knowledge of the characteristics of the specific ...

An improved process-oriented hydro-biogeochemical model for simulating dynamic fluxes of methane and nitrous oxide in alpine ecosystems with seasonally frozen soils [PDF]
Biogeosciences, 2021 The hydro-biogeochemical model Catchment Nutrient Management Model – DeNitrification-DeComposition (CNMM-DNDC) was established to simultaneously quantify ecosystem productivity and losses of nitrogen and carbon at the site or catchment scale.

Ozone weekend effects in the Beijing–Tianjin–Hebei metropolitan area, China [PDF]
Atmospheric Chemistry and Physics, 2014 The ozone weekend effect (OWE) was first investigated in the metropolitan area of Beijing–Tianjin–Hebei (BTH), China, using in situ measurements from the Atmospheric Environment Monitoring Network from July 2009 to August 2011.

A two-way coupled regional urban–street network air quality model system for Beijing, China [PDF]
Geoscientific Model Development, 2023 Owing to the substantial traffic emissions in urban areas, especially near road areas, the concentrations of pollutants, such as ozone (O3) and its precursors, have a large difference compared to regional averages, and their distributions cannot be ...

Acoustic boundary layers as boundary conditions [PDF]
Journal of Computational Physics, 2018 The linearized, compressible Navier-Stokes equations can be used to model acoustic wave propagation in the presence of viscous and thermal boundary layers. However, acoustic boundary layers are notorious for invoking prohibitively high resolution requirements on numerical solutions of the equations.

Wet and dry deposition of atmospheric nitrogen at ten sites in Northern China [PDF]
Atmospheric Chemistry and Physics, 2012 Emissions of reactive nitrogen (N) species can affect surrounding ecosystems via atmospheric deposition. However, few long-term and multi-site measurements have focused on both the wet and the dry deposition of individual N species in large areas of ...

Modeling the Impact of Atmospheric Warming on Staple Crop Growth in China in the 1960s and 2000s
Atmosphere, 2020 Responses of crop growth to climate warming are fundamental to future food security. The response of crops to climate change may be subtly different at their growing stages.
